The Delay Tolerant Networks (DTN) approach is
considered the best strategy to address the specific issues of
the VANETs, namely high mobility, variable node density or
frequent radio obstacles. Several protocols have been proposed
for DTNs, being the epidemic routing (and variations of it)
the most representative protocol. Nevertheless, the availability
of navigation systems, thanks to which each vehicle is aware of
its location within a map, introduces the possibility for a new
routing approach, known as Geographic Routing.
In this paper we analytically evaluate the performance of our
previously presented Map-based Sensor-data Delivery Protocol
(MSDP). We introduce an analytical model that takes into
account the effect of constrained buffers. The results show that
adopting the Map-based Sensor-data Delivery Protocol (MSDP)
routing mechanism allows achieving a reasonable delivery time
with an insignificant overhead compared with epidemic routing.[-]
